BLOCK-MOLD.

Specification of Letterslatent.

Application filed June 6, 1910.

, Patented Mar. 7, 1911.

Serial No. 565,207.

T all whom it may concern:

Be it known that we, CHARLIE CARTER and SOLOMON MILLER, citizens of theUnited States, residing at Bone Gap, in the county of Edwards and Stateof Illinois, have invented certain new and useful Improvements inBlock-Molds, of which the following is a specification.

Our present invention relates to block molds of the expanding andseparable type, our object being to provide a simple and inexpensiveconstruction in which to mold tapering blocks, and one which will bestrong and durable and wherein the parts may be readily and quicklyreplaced, the principal use of which blocks is to form foundation stonesfor frame buildings, such as barns, granaries, corn-cribs and the like,under which the blocks are placed vertically with their larger ends setinto the supporting surface.

with this in mind, our invention resides in the features of constructionset forth in. the accompanying drawing, in which,

Figure 1 is a side elevation of the assembled mold, Fig. 2 is a planview thereof, Fig. 3 is a longitudinal section therethrough, Fig. 1 is atransverse vertical section therethrough, taken on line ea of Fig. 1,and Fig. 5 is an. enlarged detail of a fragment of one of the sides.

Referring to these figures, the base 10, of the mold, has equi-distantlyspaced bearing blocks 11 upon its under surface, and secured theretotransversely thereof, the ends of said blocks having U-shaped members 12secured thereto. The sides 13, of the mold, have vertical bars 14l-.secured upon their outer surface to coincide with the members 12, thelower ends of said bars being tapered and bent outwardly to form locks15 which ongage the U-shapcd members 12 when the lower edges of thesides 13 are placed in position along the longitudinal edges of the base10. The inner faces of the sides 13 are provided with transverselyalined pairs of downwardly converging angle bars 16, to receive,thereagainst, the partition plates 17 extending between the sides 13 andwhich are tapered in accordance with the flare of the sides as shown.The upper edges of the sides 13 are provided with a plurality of slots18, these slots being located at the ends of the sides and between eachpair of angle bars 16, and being adapted to receive therein theconnecting bars 19 which extend through the sides 13 and have.transverse pieces 20 at one end and have their opposite ends apert-uredto receive locking pins or keys 21, con nected loosely thereto by chainsThese bars 19, being rigid, thus serve to connect the upper edges of thesides 13 without interfering with the mold spaces, that is, the spacesbetween the partition plates 17 of each pair. The parts thus formed maybe readily and quickly placed together and taken apart, and theconnecting members of the sides and base, while strong and lasting, maybe readily removed when damaged, and others put in their place.

We claim:

The combination of a base, upwardly extending and outwardly flaringsides, relatively engageable means carried by said base and sides toconnect the lower edges of the latter upon the-sides of the former,angle bars secured in alined, downwardly converging pairs upon the innersurfaces of said sides, )artition plates disposed against said bars,said sides having slots in their upper edges at their ends and betweeneach pair of said angle bars, and connecting members extending throughthe said slots, having means to engage the outer surfaces of the sidesto prevent the same from s n'eading.

In testimony whereof we afi'ix our signatures in presence of twowitnesses.
